Patent CA-2075265-A1 (CA)
Inventor: SARKOZI JEFF
IPC: A43B7/14
Filed: 1992-08-04
Abstract: A deformable,  elastic insole liner is provided with height adjustment pads for shoes to independently support the heel area, the longitudinal arch area, and the metatarsal arch area.  Each pad comprises a base pad and a plurality of thin stacking pads which completely overlay the base pad and any stacking pads, and are self stabilized thereby.  The stacking pads may be removably stacked onto each base pad, without requiring a fixed means of attachment to each other, in order to achieve the proper height adjustment for an individual user.  This enables an individual shoe to be separately height adjusted for any combination of heel, longitudinal arch and metatarsal areas.  In addition, after an initial adjustment, a particular support can be further height adjusted after a period of time, as necessary.  This enables the user to adjust a shoe to treat the initial support problem, and subsequently to readjust the support for ongoing changes in the arches and heel areas.

Abstract: A B S T R A C T           A shear plug connector arrangement is formed by a bearing element (1) and a plug element (2) that can be introduced into the bearing element.  The bearing element (1) comprises an outer sleeve and an inner sleeve (3 and 4, respectively).  Between these two sleeves (3, 4), an elastic element (5) is arranged.          The inner sleeve (4) and thus the plug element (2) introduced therein are mounted in floating fashion.          This leads to a good footstep sound insulation.  In accordance with the invention, means (7, 8, 9) for limiting motion amplitudes are provided at the bearing element (1) and/or at the plug element (2) so that the elastic element is not subject to excessive stresses and to ensuing short-term or long-term damage.  The afore-mentioned means are realized, for example, by an annular disk (8) on the front face of the inner sleeve (4), a nail plate (7) having a circular opening at the outer sleeve (3), and an interposed gap (9).          The plug element (2) has a good inherent damping since it is constituted by a plug sleeve (11), a plug core (12), and a filling material (13) provided between sleeve and core.

Filed: 1993-02-12
Abstract: Disclosed is a process for preparing a solid, light weight mineral foam which is stable during its preparation and during its subsequent curing and drying and which, thanks to its composition and the way it is prepared, can be injected in situ, substantially like a urethane foam. This foam has a density ranging from 10 to 65 lb/pi 3 and is made of 1 part by weight of a solution of phosphoric acid of given concentration in which is dissolved polyvinyl alcohol in such an amount as to make the solution viscous; from 0.03 to 6 parts by weight of wollastonite containing from 0.5 to 4% by weight of a carbonate salt; and from 0.2 to 10 parts by weight of water. The amount of water depends on the concentration of the solution of phosphoric acid and of the required density of the foam, it being understood that the more concentrated is the solution of phosphoric acid and/or the lower is the required density, the higher is the amount of water. The products made of such a foam are rigid and can be used for thermal and acoustic insulation.

Filed: 1993-02-19
Abstract: A B S T R A C T          A spacer for structural elements such as wall studs comprises a main plate with side flanges extending along its longitudinal edges.  Alignment tabs are struck perpendicular to the main plate, and locking tabs are struck from the side flanges so that the end of a stud may be press-fitted against the alignment tab and locked into place by the locking tabs.  A pair of such spacers oriented in opposite directions act as a top plate and shoe for a wall frame, into which a stud can be inserted by tilting the stud and aligning it with the space between the side flanges, and then righting the stud to press-fit its ends into locked engagement with the spacers.

Title: Heated injection molding nozzle with alternate thermocouple bores
Inventor: GELLERT JOBST U
IPC: B29C45/27
Filed: 1993-11-10
Abstract: A heated injection molding nozzle having a melt channel which branches outwardly to several spaced edge gates. The nozzle has alternate thermocouple element receiving bores spaced longitudinally along a temperature gradient extending between the heating element and the front end of the nozzle. The nozzle facilitates the temperature control of materials having different thermal characteristics. When molding an amorphous material, a temperature somewhat lower than the prescribed operating temperature is desirable so the thermocouple element is mounted in the rearward bore closer to the heating element.      If it is critical to maintain the temperature of the melt near the prescribed operating temperature for a material such as a crystalline material, the thermocouple element is received in the forward bore further along the temperature gradient from the heating element.
